Vladmir Jurowski and the London Philharmonic Orchestra have been to the bottom of the Rhine before, but in 2015 only did a whistlestop tour of the rest of Rheingold's terrain with an extensive array of excerpts.

It seems they’re having trouble with the lights. Thirty-five past five and they’re not yet on. “Typical,” laughs a woman, surveying the huddle of hi-vis chaperones. Palm fronds wave in the wind, suits leave work. St James’s Square slowly fills with people. The huddle of technicians breaks up and in a short moment, candy coloured bulbs strung in rainbow belts between plane trees light up and everyone goes “Oooooh” and gets out their phone.

Did Simon Rattle's return to the UK as Principal Conductor of the London Symphony Orchestra live up to the hype? Mostly, and when it did, the music-making was superbly alive. But it's vital to observe that another orchestra and chief conductor have been carrying on equally important and sometimes groundbreaking work in the same hall.

Just when you can scarcely move for Messiahs, two Christmas Oratorios came along at once on Saturday night. That’s London concert schedules for you. While John Butt and his Dunedin Consort unwrapped four of the cantatas at the Wigmore Hall, Vladimir Jurowski presented all six. Was it too much of a good thing?

After Sakari Oramo's dazzling Sibelius rattlebag with the BBC Symphony Orchestra on the centenary day of Finnish independence, things weren't looking so good for Esa-Pekka Salonen and the Philharmonia at half time last Thursday (★★★). Then along came the Four Lemminkäinen Legends, an early Sibelius masterpiece teeming with invention and strangeness, long a Salonen speciality.

When you've found your living ideal for Schubert's sonatas - Elisabeth Leonskaja, surely - it can be a challenge to stay open-minded and welcome another take on the profundities.

This concert was to have been conducted by Stanisław Skrowaczewski, who died in February. Though futile, it’s hard not to speculate about what could have been, especially given his spectacular Bruckner performances with the London Philharmonic in recent years. But life goes on, and in his place we heard Lawrence Renes, whose account of Bruckner’s Eighth Symphony was solid and dependable, even if it was more memorable for the quality of the orchestral playing than for his interpretive insights.

Such introspective subtlety might be mistaken for reticence. But from the rare instances when the Norwegian pianist Leif Ove Andsnes lets rip - and they're never forced - you know he's wielding his palette with both skill and intuition, waiting for the big moment to make its proper mark. Flyaway passages in Chopin which in other hands bubble like pure champagne flow like pure spring water; the source is everything.

A legendary name and the chance to change the face of a cruel condition set the stakes high for what Prince Charles, in his programme preface for this Southbank spectacular, told us was called the Stop MS Jacqueline du Pré Tribute Concert.

The Royal Festival Hall rather belied its name for a visit to London on Saturday of France’s premier new-music ensemble. It can’t be helped that the more intimate space of the Queen Elizabeth Hall next door is presently closed for renovation, but with the balcony and back of the stalls both empty and unlit, the place presented a more dismal aspect than usual.
